APPARATUS FOR SATURATING LIQUIDS WITH GASES.

To all whom it may concern Be it known that we, JAcoB F. WITTE- MANN and RUDOLPH WV. WITTEMANN, citizens of the United States, and residents, respectively, of Lakewood, Ocean county, State of New. Jersey, and Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Apparatus for Saturating Liquids with Gases, of which the following is a specification.

This invention relates to a new and improved apparatus for saturating liquids with gases, such apparatus being used for the aeration, carbonation and similar treatment of beverages, and for treatingliquids with a gaseous medium, such apparatus being most commonly used for saturating or impregnating beverages with the volatile products of fermentation, and in this specification we will use the term carbonating apparatus as a generic name for such apparatus.

The object of our invention is to provide a new and improved carbonator which is compact, strong, and simple in construction, and rapid, reliable and effective in operation.

In the accompanying drawings in which like letters of reference indicate like parts in all the figures: Figure 1 is an elevation of one embodiment of our improved carbonating apparatus, parts being broken away and others shown in section. Fig. 2 is an elevation of the spiral conduit plate.

The entire apparatus is mounted on a suitable base or foundation 1 on which is secured an electric motor 2 of any approved construction which rotates a pulley or sprocket wheel 3, which by means of an endless belt 1 rotates the pulley 5 of a rotary pump 6 acting as a compressor secured on the base. The pump has a horizontal cylindrical casing in which the hub 7 is mounted eccentrically to rotate, said hub having four equi-distant wings 8 extending lengthwise of the compressor casing and between each two wings a vane 9 is mounted so as to swing toward and from the axis of the hub and the interior circumference of the easing. The hub is so mounted that the outer face of each wing 8 successively comes into contact with the interior circumference of the casing at a point about midway between Serial No. 644,246.

the upper end of the vertical axis and the left hand end of the horizontal plane through the casing as indicated at 10. \Ve do not lay claim to this particular construction of a rotary pump acting as a compressor, a rotary pump of this type being shown and described in the U. S. Patent No. 869,050 to R. M. Blackmer, issued Oct. 22, 1907 The compressor casing is provided with a horizontal inlet neck 11 which is coupled to a neck 12 of the liquid suction chamber 13 which is divided into two compartments by a vertical perforated partition 14; and is provided at the bottom opposite the neck 12 with a neck 15 to which the liquid supply pipe 16 is coupled. It will be seen that the liquid entering through the neck 15 must necessarily pass through the perforated partition 14: whereby it is screened and coarse material is prevented from entering the pump. Between the neck 11 and the pump casing at the point 10 where the outer faces of the wings connect with the inner circumference of the casing an additional neck 17 is connected with the pump casing which neck leads to a gas suction chamber 18 preferably made of glass and containing a buoyant check valve 19 and a regulating cook 20, the gas being conducted to said gas suction chamber 18 by a gas suction supply pipe 21. As the gas suction chamber is made of glass the operator can at once discover any liquid which might happen, by accident, to pass into this gas suction chamber. At the top, the pump casing is provided with a vertical discharge pipe 22 which extends upward into a reservoir chamber which is closed at the top and is provided near its bottom with an outlet neck 23 to which a suitable tube 24: is coupled for carrying off the carbonated or saturated liquid. The reservoir chamber is composed of a base section 241 and a detachable dome or top 25through the closed top on which a screw rod 26 is screwed which terminates in a cylindrical dash cap 27 mounted slidably in the vertical discharge tube 22 of the pump. This cylindrical dash cap is provided in its upper part with the slots 28 and on the underside of the top of the dash cap an inverted cone shaped or tapered liquid deflector 29 is formed. A spiral plate 32 is arranged within the chamber 25 between the mner surface of the same and the Patented Nov. 17, 1914.

outer surface of the vertical discharge pipe so as to compel the liquid discharged from the upper end of the discharge pipe to travel through a spiral or helical conduit before it passes into the base part 24: of the reservoir chamber thereby causing a more intimate mixture of the gas and liquid, for example, fermentation gas and beer, that is, a more perfect saturation. The base part 2 1- of the reservoir chamber is provided with a neck 30 terminating within the same compartment of the liquid suction chamber 13 with which the neck 12 is connected and this neck 30 is normally closed by an adjustable spring pressed relief valve 31 so that when the pressure in the reservoir chamber rises beyond the determined de gree the relief valve 31 is lifted and part of the liquid that has been discharged from the compressor will be delivered into the liquid suction chamber to be again passed through the pump and so on.

As the pump is operated and its wings and vanes rotate they draw in liquid from the liquid suction chamber 13 and gas from the gas suction chamber 18 and the liquid and gas, such as beer and fermentation gas, are thoroughly commingled and as there is constant pressure against the action of the pump this mixture is compressed, that is to say, the liquid and gas are united. It will be observed that as the wings come in contact with the shell or casing of the pump at 10 that the mixture of the gas and liquid is prevented by such contact and by the contact of the vanes within the inner circumference of the casing from passing into the gas neck 17 which conducts gas from the gas suction chamber and the vane 9 directly beneath the wing which is in contact with the inner circumference of the casing prevents the liquid passing into the pump from rising up into the gas inlet neck. It will also be observed that gas is admitted in advance of the liquid. It will thus also be observed that the liquid and the gas which are to be mixed and compressed by the rotary pump are both conducted to the point of impact or suction in said pump, that is to the point at which the action of the pump upon the fluids for the purpose of compressing the gas begins and this point we have defined as the polnt of impact or suction of the pump. '1he rotating pump, after thoroughly mixing the gas and liquid forces them up through the vertical pipe 22 whence this column of mixed liquid and gas is dashed against the inverted conical or tapered deflector 29 whereb; this mixture is atomized, and forced through the slots 28 of the cylindrical dash-cap 27, causing the liquid to absorb the gas which accompanies it in its passage through said reservoir chamber and then the liquid and gas are 1o1ntly forced Having described our invention what we claim as new and desire to secure by Letters Patent is 1. In a carbonating apparatus, the combination with a cylindrical casing having an outlet at the top, a liquid inlet at the side, and a gas inlet between the liquid inlet and the said outlet, of an eccentric rotary hub having wings and vanes within said chamber, the said eccentric rotary means being so mounted that the wings successively contact with the inner circumference of the casing at a point between the said outlet and the gas inlet, substantially as set forth.

2. In a carbonating apparatus, the combination with a rotary pump having independent inlets for gas and liquid, and an upwardly extending outlet reservoir chamber surroundingsaid outlet, of a spiral conduit formed within said reservoir chamber and an outlet neck for said reservoir cham* ber, substantially as set forth.
